With durable metal construction and a compact profile, it’s a solid choice for workshop and industrial compressed-air setups where tidy routing and reliable sealing matter.

Features

Straight union design Joins two tubes in-line for a clean, compact air line connection.
4mm push-in ports (both ends) Fast, secure tube fitment for quick assembly and maintenance.
Metal construction Durable body built for everyday workshop pneumatic use.
Compact profile Fits neatly into tight installs and tidy cable/air management routes.

Benefits

Fast repairs; Restore a damaged air line section without replacing the entire run.
Easy extensions; Add length to 4mm tubing quickly and keep routing neat.
Reliable seal; Secure push-in grip helps reduce leak risk in your compressed-air system.

Extra Information

Use clean, round 4mm pneumatic/PU tubing and ensure cuts are square before inserting.
Push the tube in fully until it seats, then do a gentle pull-back test to confirm it’s locked.
After installation, pressurise slowly and check for leaks using soapy water.

Pro Tip

If a tube end is scratched or oval, trim it back and re-cut square—push-in fittings seal best on a clean, undamaged tube end.
